Microsoft included this shutdown jingle with Windows 98, released in 1998 as the successor to Windows 95. The sound played automatically during the shutdown sequence on millions of home and office PCs throughout the late nineties and early 2000s. As those machines disappeared, the jingle survived on YouTube nostalgia compilations, meme pages and soundboard sites where users collect classic operating system audio. It remains popular because it instantly signals retro computing, making it a quick audio shorthand for old technology, dial-up era memories and gentle comedic endings.
